Definitions
- Injection molding machine for processing plasticizable materials.
- the invention relates to an injection molding machine for processing plasticizable materials such as of plastics, powdery masses or ceramic masses according to the preamble of claim 1.
- Eirte-L-er-rrtige 5p ⁇ itzg cashmaschine is known for example from DE-A 20 20 336 on which the preamble of claim 1 is based or from DE-C 32 14728, by means of an injection molding unit not only via an injection opening provided on the mold into the mold cavity to be able to inject the injection mold, but also to inject into the parting plane if necessary. Swiveling the mold clamping unit into a vertical position is also an advantage when working with inserts. At the same time, this creates the basic requirements for injecting via the central sprue opening and into the parting plane by means of two injection molding units.
- the present invention has for its object to develop an injection molding machine of the type mentioned in such a way that pivoting into the Different positions of the mold clamping unit is made possible inexpensively with as few drive devices as possible.
- the drive unit is arranged in an articulated manner, the desired effect of carrying out all the necessary movements with only one unit being produced by the distance relationship between the pivot axis and the articulation point of the drive unit.
- Fi g. 2 shows a section along line 2-2 of FIG. 1,
- Fi g. 3 is a view according to FIG. 1 with a mold clamping unit in the process of pivoting
- FIG. 4 shows a view according to FIG. 1, the mold clamping unit being transferred to the vertical position
- Fig. 5 shows a view according to FIG. 1 with a vertically standing mold closing unit, in which the parting plane is set to the height of the injection molding unit. Best way to carry out the invention
- Fig. 1 shows a section of an injection molding machine, in particular a plastic injection molding machine, which is used to process plasticizable materials such as of plastics, powdery masses or ceramic masses is provided.
- the plasticizing cylinder of the injection molding unit S which passes through the stationary mold carrier of the mold clamping unit, is indicated at the top right.
- the injection molding unit S and the mold closing unit F are arranged on a machine base 10.
- the mold clamping unit receives a casting mold M (FIG. 3) between a movable mold carrier 11 and a stationary mold carrier 12.
- the movement of the movable mold carrier 11 takes place via a closing device 13, which e.g. works hydraulically or electromechanically.
- the closing device moves the movable mold carrier 11 of the mold clamping unit F towards and away from the stationary mold carrier 12 along a closing axis s-s.
- the mold clamping unit In order to enable the mold clamping unit to be pivoted, it is arranged on support elements 15, which combine at least the movable mold carrier 11, the stationary mold carrier 12 and the closing device 13 of the mold clamping unit F to form a structural unit.
- the closing device 13 is supported on a support element 14, which is connected to the stationary mold carrier 12 via bars 16.
- differently shaped power transmission elements can also be provided, which, for example, allow free access to the mold clamping space and are guided around it.
- the structural unit is supported on the machine base 10. About a transverse axis to the closing ss extending pivot shaft 1 5 is the structural unit at least 90 ° relative to the machine 10, preferably from a horizontal position according to FIG. E * ine in vertical position according to FIG. Pivotable.
- guides 20 are provided. This is particularly necessary in order to bring the parting plane to a height at an injection into the parting plane, in which the injection axis of the injection molding unit S lies.
- means are provided for pivoting the structural unit about the pivot axis 18 and means for displacing the structural unit along the guides 20.
- a drive unit A is provided as a means for pivoting and, if necessary, shifting the structural unit, which is articulated to the machine base 10 and at an articulation point 21 to the structural unit. The articulation point 21 is spaced from the pivot axis 18.
- the articulation point 21 lies above a line which is laid through the pivot axis 18 and the pivot point 28 of the drive unit A.
- the direction of action of the linear drive designed as drive unit A is almost at right angles to the guides 20 when the structural unit is arranged horizontally.
- the linear movement means 22 of the drive unit engages on the support member 15 of the structural unit.
- the structural unit is transferred from the horizontal position according to FIG. 1, the structural unit is first pivoted into a vertical position according to FIG. 4 and then moved upwards in the guides 20.
- the pivot axis 18 is in the horizontal position of the structural unit above the articulation point 21 on a support arm 23 supported on the machine base 10.
- Fig. 1 illustrates that the pivot axis 18 is at a greater distance from the stationary mold carrier 12 when the structural unit is in a horizontal position than the articulation point 21.
- the arrangement of the pivot axis 18, the pivot point 28 and the articulation point 21 is selected so that the desired movement sequence results in pivoting-displacement . This arrangement is optimized so that access to the mold clamping space is not impaired.
- the drive unit A and the pivot axis 18 are in the horizontal projection of the mold clamping unit in the area of the vertical projection of the mold clamping space between the movable mold carrier 11 and the stationary mold carrier 12.
- the pivot axis 18 and the articulation point 21 are both in the horizontal and in the vertical mold clamping unit F each Area of a projection of the mold clamping space delimited by the mold carriers in their respectively open position.
- the horizontal mold closing unit is a vertical projection and the vertical mold closing unit is a horizontal projection.
- FIG. 4 shows, in particular in comparison with FIG. 5, that in this position injection from the injection molding unit S is not yet possible under circumstances which are essentially determined by the shape dimensions.
- the mold clamping unit has to be moved upwards, which is also done with the same drive unit.
- an electromechanical spindle drive is provided as the drive unit, wherein according to FIG. 2 a motor 27 drives two spindle drives synchronously via a drive shaft 29.
- a motor 27 drives two spindle drives synchronously via a drive shaft 29.
- an electronic shaft can also ensure that the spindle drives are synchronized, provided that a separate motor is provided for each spindle drive.
- only one motor can also be used, but this should then preferably act centrally on the mold clamping unit.
- the electromechanical drive other types of drive can also be provided.
- the machine can also be provided in a simplified embodiment, in which the electromechanical drive is replaced by a manual drive, for example by means of a crank.
- the scale 26 is then particularly advantageous in the case of such an embodiment since it can be used to specifically determine the measure for the height adjustment of the parting plane.
- An optimal pivoting occurs when the pivot axis 18 is placed as far as possible on the closing axis ss in the horizontal position or in the vertical position on an axis through the parting plane t-t. In this case, the displacement can possibly be dispensed with, but if the corresponding guides 20 are provided, a more precise adjustment to different shape dimensions is possible.
- an injection molding unit S ' can be pivoted with the stationary mold carrier 12, while a second injection molding unit S is arranged on a table 30 and can be placed on the injection mold M on this table 30 after setting the parting plane.
- FIGS. 3 and 4 clarifying that the pivoting takes place in a recess in the machine base 10.
- the linear movement means 22, in the exemplary embodiment a spindle, is protected against contamination by a protective element 24.
